WindowsMegabyte in general

The purpose of WindowsMegabyte is to show unwanted advertisements and promote a fake search engine. It could be capable of collecting browsing data or other information as well. There are plenty of examples of similar apps. Some of them are NetworkService, LinkInfo, and PathNetwork.

How did WindowsMegabyte install on my computer?

Adware is distributed by bundling it together with other programs, through ads designed to execute certain scripts, fake installers. In the first case, users download or install adware when they leave "Advanced", "Custom" or other settings available in downloaders or installers unchanged.

Fake installers usually are designed to look like installers for legitimate programs, updates. Most of them are promoted through deceptive pages.

How to avoid installation of potentially unwanted applications?

It is recommended to use legitimate sources such as official pages to download applications and files, not other sources. Advertisements appearing on dubious pages should not be clicked as well.

One more way to avoid unexpected downloads or installations is to check downloaders and installers for unwanted applications before downloading and installing programs.

If your computer is already infected with WindowsMegabyte, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
